Jesus, according to Islamic belief, was a great prophet, but he did not die as the Christians (and secular historians) believe.

You can read more about this in my post "Did Jesus Die?"

There is another problem raised with this assertion that Jesus did not die, and that he was a great prophet.  Jesus predicted his death many times, even detailing the manner.

Mark 8:31 "And He began to teach them that the Son of Man must suffer many things and be rejected by the elders and the chief priests and the scribes, and be killed, and after three days rise again."

Mark 9:31 "For He was teaching His disciples and telling them, "The Son of Man is to be delivered into the hands of men, and they will kill Him; and when He has been killed, He will rise three days later.""

Mark 10:33-34 ""Behold, we are going up to Jerusalem, and the Son of Man will be delivered to the chief priests and the scribes; and they will condemn Him to death and will hand Him over to the Gentiles. "They will mock Him and spit on Him, and scourge Him and kill Him, and three days later He will rise again.""

These verses are just from Mark, similar ones are found in the other 3 gospels.

So if Jesus predicted his own death, and according to Muslim belief, he never died, then Jesus was not a great prophet, but instead a false prophet and a liar.

At this point Muslim belief must deny the Bible without any supporting evidence to do so, just to maintain their belief.  Again using a document written 600 years after the events to overturn eye witness evidence recorded in the same time period of Jesus' death.
